PHENTiNG AND EMBOSSING APPARATUS.

-' Specification of Letters Patent.

Patented April 2, 1907.

Application filedJannary 25,1908. Serial No. 297,809.

To all whom it may concern.-

Be it known that I, EDWIN E. ANGELL,

of Somerville, in the county of Middlesex' and State of Ma'ss aeliusettshave invented certain new and useful Improvements in Printing and Embossing Apparatus, of which ior ineif aceably indicating the monetary value of checks, .bonds, certificates, and other commercial papers to prevent alteration Its object is to provide a machine or 'apparatus of simple construction which will emboss the figures or other characters on the sheet and at the same time deposit ink or other coloring-matter on both sides of the sheet, the embossing having the effect of somewhat stretching the paper over the area on which the color is deposited, so that the color will be more or less visible through the paper, whereby any attempt at erasure will cause an increased amount of color to be visible, and so such attempt will be frustrated and detected.

The object thus is to practice the method and produce the article described and claimed in my pending application Serial No. 274,047, filed August 14, 1905.

vIncarrying out my invention I provide cooperating dies or types arranged in twosets or series, those of one set being raised to impress or emboss the sheet, while the dies of the other set are recessed in their central portions to receive the raised dies and to imprint the outlines of the characters on the. surface o the sheet immediately surrounding the pa] ts thereof which are displaced or distorted by the raised dies.

These and other features of construction of the apparatus are described and claimed in' the following specification and are illustrated in the accompanying drawings, in whiching toward the front.

from that illustrated in Fig. 2. Fig. 6 represents a front elevation with the upper part of Figs. 7 and 8 reprethe casing in section. sent detail plan views of parts of the mech-i anism. Fig. 9 represents a detail elevation of the feed mechanism for the sheet upon which the impressions are made. Fig. 10 represents a detail sectional View on line 10 1.0 of Fig. 2. Fig. 11 represents a plan view of a fragment of a sheet, showing, on an enlarged scale, the appearance of characters impressed thereon by this apparatus. Fig. 12 represents a section on line 12 12 of Fig. 11.

Fig. 13 represents a vertical transverse section, on an enlarged scale, of a pair of opposing printing and embossing dies.

The same reference characters indicate the same parts in all the figures.

The mechanism of the I apparatus is inclosed in a box or casing 1, which is divided into two parts by a flat horizontal partition 2, which constitutes a support for the sheet of paper or other material which is to' be printed upon. The upper part of the casing consists of a detachable cover 3, held in place by lugs 4, through which andthe Walls of the cover screws may be passed. I

Secured to the wall 2 is a support 5, which is fastened by screws 6 and extends forwardly from the ointofattachment over the work-supporting wall, being separated;-

therefrom by a space 7, which permits a sheet of paper laidupon the wall 2 tobe in sorted under the support 5.; Thesupport 5 supports a die holder or'head 8,. which is preferably cylindrical and carries on its outer or cylindrical portion a plurality of 'marking dies or types 9, which when the holder is r'otated are brouglit successively into position gears 12 13 from a vertical shaft 14, one of said bevel-gears'being on shaft 10 and the other on shaft 14.

Beneath the dividing-wall 2 is a'second' support or bracket 15, which has bearings 16 16 for a shaft 17, on the end of which is mounted a second rotary holder or head 18, similar to the holder .8, which carries marking dies or types "19. The shafts and 17 carry, respectively, gears 20 21, which mesh together, so that when the first is turned the second is correspondingly turned at the same time, and thereby the-dies carried by each holder are shifted in unison. The dies or types carried by the holders represent certain definite characters-such as figures, letters, or conventional signsand those on one holder correspond to the characters on the other and are similarly though oppositely arranged. Thus when one holder is in position to bring a. certain character in position to mark the paper the other holder has the same character in position to mark upon the other side of the sheet. The dies 9 are re cessed within the outlines of the characters, while those of the holder 18 are raised and designed so as to enter the depressions in the corresponding dies 9 when the hold as are brought together. The raised portions 191 of the lower dies 19 are flat and adapted to receive ink, which when the dies are brought against the paper is deposited on the latter in solid masses which have the shape of conventional characters. On the dies or types 9 the narrow projecting sur faces which surround the recesses made to receive the protuberant lower dies are in one plane and receive ink, so as to deposit the same on narrow lines that surround and inclose the raised characters which are offset by the protubcrant dies when the latter cnter and force the paper into the recesses of the on tline dies;

In order to permit relative approach and separation of the die-holders, the bracket is pivoted to the upper support 5 on \an axis 22, which passes through the central point of contact of the gears 20 21, so that although the bracket 15 may oscillate the gears are retained at all times in mesh with each other, and when shaft 14 is rotated both the gears 20 and 21 are turned and both sets of dies correspondingly shifted, although they are out of engagement.

The means for rotating, and ther-by adjusting, the die-holders consists of a lever 23, pivo'tally mounted so as to turn about a stud 24, secured to the bottom of the casing, and the'rcar arm of which carries a segment of a gear 25, meshing with a pinion 26, secured to shaft 14. Upon the forward a rm of lever 23 is pivoted between lugs 27 an operating arm or handle 28, provided at its forward end with a linger-piece 29. 'lhe-re'arwa:"d-cnd ot' operating-arm 28 is located directly aliove the pivot 24 and enters a recess 30, formed between the body of bracket 15 and a tongue 3]. When the peratmg hamlle' is moved laterally to right or left, it turns lever 23 and" rotates the die-holders through the connections above described; but lts rear end does ment with the bracket .15. When, however,

not change position and remains in engagethe handle 28 is moved down around its pivot 32, its rear end is raised, whereby the bracket 15 is oscillated and die holder 1 is raised to bring its uppermost die or type through a slot 33 in the supporting wall or table 2 and into contact with a sheet laid. thereon. Separation of the dies isellected both by the weight of the lower di holde and also by a spring 34, inclosed within a tubular socket 35 on the lever 23 and bearing against handle 28.

The die-holder 18 has a laieral flange 36, provided with slots or notches 37, which are spaced correspondingly to the spacing of the dies 19. 3b is a stationary linger projecting from the under side of wall 2 in position to enter the notch 37, which may be under it when the lower die-holder is raised. in case one of the notches is not directly beneath the locking projection the latter is engaged by the flange and the holder is thereby arrested before it has been raised far enough. to. touch the sheet, and it cannot be raised farther until it has been shifted so as to bring one of the notches adjacent the lock. Thereby it is impossible to print u on the sheet except when the dies are in t 1e position necessary to make a correct impression, and this lock having once entered a notch prevents the dies being shifted while they are in contact with the paper. Thus it is impossible t-o'spoil an impression once made.

As a means for guiding the operating-ham dlc laterally into a position which will adust the dies correctly I provide notches 39 in the front wall 40 of the casing The lower )ortions of these notches are just wide enougli to permit the arm 28 to enter them, while the upper portions are widened and flared outwardly, so that one merges into the other. Thus no matter what position the operati garm may be in when raised as soon as it is depressed it enters one of the notches and is guided thereby to bring the dies into correct adjustment for printing. The notches 39 are spaced so that when arm 28 is in one of them the locking pro ection 38 is in one of the notches 37 and the dies or types are exactly parallel with the paper.

On the forward top wall 41 of the casing a line of index characters 42. corresponding to 'the characters on the dies or types and arangcd so that when the operating-arm is undcr any one of the i1 idex characters the dies 9 a nd,] 9 bearing the corresponding charactewv are adjacent eacliothcr and in the line of centers of the die-lmlders. In the machine illus trailed, which is adapted to print money values upon checks and other forms of commercial paper to prevent raising of the face values, the characters represent the numerals from 1 to 0," inclusive, and also the signs representing dollars, pounds sterling, and francs.

--lnk (mother coloring-matter is supplied to the'uppcr'sct of dies by means of rollers 43,

849,038 iii...

jo'urnaled in hangers 44, suspended .from pivots 45 in lateral arms 46, extending from the upper part of support 5. Thesehangers are drawn toward each other and the holder 8 by springs 47, whereby the ink-rolls are retained in contact with the dies, andas the.

, holders are rotated successive dies are brought toe of the latter-against t e ratchet.

against the rolls. An arrn'44 extends from each of the hangers, and thesearms are held against eccentric pins 46' "on screws 46", tapped into the arms 46 by said springs 47. Adjustment of these screws limits the pressure with whielrthe rolls are held against the dies, so that the ink will not vbe squeezed out too copiously, and also permits sui'licient pressure to be maintained-when the rolls have been reduced indiamet'er by wear. Similar ink-rolls 48 'are'mounted in holders 49, pivoted to arms 50, extending laterally frornthe bracket 15 and held in engagement with the dies 19 by springs'51.

For feeding the sheet between impressions of the dies I provide one or more serrated or. knurled feed-Wheels 52 on a shaft53, which.

also carries a ratchet-wheel"54. An arm 55 is loosely' journaled on' shaft 53 andparries a stud 5 6, onwhich is pivoted a and 57 in'pos1 A spring 58 surrounds the stud 56, hearing at one end against the arm 55 and at the other upon a projection of the awl, and retains the Arm 55 has a-slot 59, into which'exten'ds the end ofa rod 60, carried by the pivoted die-holder bracket 15. When the latter is raised to impressthle pa er, arm 55, and pawl are carried over one of t ie teeth of the ratchet, and when the die-holder is lowered away from the paper its weight causes the arm to turn in theoppo- 4 site direction, and therefore to turn the ratchet through the space. of one or more teethand advance thefeed-wheel a step. 'Ilhiscarries forward the paper so as to'prespring 52*, mounted on the'casin and. bean. ing against the huh'52 of the eed-wheel. The aper isheld in c'ont'actwith the feedwhee s by a roll 61, journaled in-a forked,

holder 62 on a'ro'ck-shaft 63, to which is secured an operating finger-lever 64. When the latter is depressed, the pressur'e roll is raised and'separated fromthe feed-wheelsfso that a sheet may be inserted or removed. A

s ring 65 exerts a constant upward pull on t efinge'r-arm64 and holds the firmly'against the feed-wheels.

, As previously 'stated, the dies :o'f'the lower holder are raised,- and therefore adapted to impress the characters into the sheet and deposit solid blocks of coloring-matter while Y Thus when the dies are brought together the rerccessed ones hear at their outer edges upon pressure-roll the upper. side of the sheet, while the raised colors will appear.

under side of the sheet in the concavities of the embossed characters? Figs. 11 and 12 represent characters embossed upon a sheet 66. in which 67 represent the raised portions of the charaeters,'68 the lines of color outlining the characters entirely around the raised portions, and 69 represents the -solid color deposited in theconcavities of the characters. In embossing the paper the portions which are displaced are somewhat stretched and attenuated, though without being perforated, and there fore the color deposited by the raised types will showthrou h to some extent. Preferably different co lors'are deposited by the recessed and raised types, respectively, so that in the upper side of the sheet contrasting Attempt to erase the color on one side of the sheet'will make the paperithinner, so that that deposited on the other side will show more plainly, and thus actersmay'be on the upper holder and the recessed or'intaglio characters on the lower holder.
